TRAP.

SPECIFICATION forming part of Letters Application filed April 25,1887.

To-aZZ whom it ma concern: Be it known that I, EMILY A. STEARS, of Brooklyn, inflthe county of Kings. and State of New York, have invented new and useful Im- 5 provements in Sink-Traps, of which the following is a specification} reference being had to the annexed drawings, forming a part thereof, inwhichf I Figure 1 is a vertical transverse section of m my improved sink-trap,showing its application to a stationary wash-bowl. Fig. 2 is a plan view of the trap detached from the bowl, and Fig. 3 is a detail view of the thimble for. receiving the plug 'atthe bottom of the trap.

" I 5 Similar letters of reference indicate corresponding parts inall the views.

r The object of my invention is to provide a trap for application to wash-bowls, bath-tubs, wash-tubs, and sinks, which will permit of the an free escape of the water and will'effectually prevent the entrance of sewer-gas into the house through. the wash-bowl and sink connections, and which may be readily cleaned.

The invention consists in the peculiar con- 2 5 struction and arrangement of parts, as hereinafter described, and pointed out in the claims. Although I have shown my invention ap-' plied to a stationary wash bowl, I do not limit orconfine myself to its application to wash-.

bowls, as it may be applied in aslightly-modifled form to bath-tubs, sinks, andwash-tubs with equal advantage. The body A of the trap consists of a flaring bowl of clay or other suitable material, pro

'5 vided with a concave cover or top, B, permanently attached thereto, and having a down: wardly-proj ecting tube, 0, which extends near- 1 to the bottom of the bowl. The concave top B is provided with an annular recess at the top of the'tube O to receive the downwardly-projecting portion D of the wash-bowl E. The bottom of the bowl A is provided with an open ing, F, surrounded by acollar, a, larger than the opening and provided with inwardly-pro- 4 5 jecting' lugs 12. To the collar or is fitted a metallic thimble, 0, provided with lugs d, which enter between the lugsb and are turned to bring them into engagement with the said lugs 12. The thimble c is further secured by cement.

I The interior. of the thimble is screw-threaded to receive a plug, e, by whichthe bottom of bath-tubs, wash-tubs, 8w.

thebowl A is closed. The ihimble is screwthreaded or roughened on the exterior tore-;

ceive the cement by which itis held inplacc'in the collar a. A packing-ring, f, is placed-be- 5 5,

tween the flange of the pl'ug'eand the thimble 0., a In the side of the trap-bowl A, near the top,

is formedanopening, g, for the escape of water from the bowl, and the passage h, commu nicating with the opening 9, extends down-"6o ward and projects below the bottom of the;bowl A'in the form of. a tube. V The opening 9 determines the level of the water in the bowl A, *and the bowl contains sufficient water to ef-- fectively maintain the seal of the trap, so that thetrap is not liable to leakage fronrthe evapo ration'of the wateremployed to formthe seal. r V In the side of the bowl A, opposite the opening g and near the bottom thereof, is-formed w an opening, t, which communicates with the 0" passage j, extending upward along theoutsid'e of the bowl. The overflow 7c of the wash-bowl E is insertedin the upper end of the passage f and cemented therein. The entire length of the tube 0 isalways immersed, andtheopening '5, communicating with the passage j,'is always covered with water, so that,whether the wash-bowl E is cemented in its place 'inthe V trap-bowl-A-or not, the seal is always effectual, a

and no sewer-gas can enter the building through so the trap. t A i In the bottom of the bowl E is inserted a short flanged tube, 1, which extends downward into the tube 0 of the bowl A and receives a cross-bar or collar, m, which is pressed upward 8 5 7 instead of concave the trap may be applied to As the improved trap is made integrally of a single. piece of material, there are no joints, andconsequently no r 5 A trap-bowl constructed according to my invention and having the discharge-opening arranged at the top thereof prevents siphoning and causes the' trap-bowl to always remain filled. I j .yThe-passagej, as shown in the drawings, is v through a long tube extending from the trap By making the top of the trap-bowl Aflat' o bowl A to the overflow of the wash-bowl; but it is unnecessary to make the said tube of a single piece, as the water-seal is continuously maintained at the lower end of the passage j.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A trap-bowl having an apertured top and provided with a tube projecting downward from the inner surface of the top and integral therewith, a discharge-opening near the top, a discharge-passage communicating with the discharge-opening and extending down below the bottom of the bowl, an overflow inlet near the bottom, and a passage extending up along the side of the bowl and communicating with the inlet-opening, substantially as described.
